What Are the Plastic Screws in Car Bumpers Called?

When it comes to car repairs and maintenance, many vehicle owners might overlook the importance of the plastic screws in car bumpers. However, these fasteners play a crucial role in keeping your car’s bumpers securely attached, preventing rattles and ensuring that your vehicle looks and functions as it should. Understanding the different types of automotive bumper fasteners and how to handle them can save you time, money, and frustration when it comes to bumper repairs or installations.

In this article, we’ll dive into the various plastic screw fasteners used in car bumper installation, the types of bumper clips, and tips for DIY bumper fastener replacement. You’ll also learn how to identify the best fasteners for your vehicle and how to deal with bumper rattle fix and other common bumper issues.

What Are Plastic Screws in Car Bumpers?

Plastic screws in car bumpers are specialized fasteners made from flexible plastic materials like nylon and polypropylene. These fasteners are designed to hold various bumper components in place, including the bumper cover, trim, and fender. Unlike metal screws, plastic screws are lighter, more resistant to rust, and often more affordable, making them a popular choice in automotive applications.

These screws are specifically engineered for use in areas where corrosion-resistant fasteners are essential, especially in areas of the car exposed to moisture or road salt.

Why Use Plastic Screws?

There are several reasons why plastic screws are the preferred choice for car bumpers:

• Lightweight and Flexible: Plastic screws provide a strong yet lightweight alternative to metal fasteners, which is important for car performance and fuel efficiency.
• Corrosion Resistance: Nylon bumper screws and polypropylene screws are highly resistant to rust and corrosion, making them ideal for parts exposed to the elements.
• Cost-Effective: Plastic fasteners are typically cheaper than metal alternatives, which helps to reduce production costs for car manufacturers.
• Durability: Despite being lightweight, these fasteners can handle a significant amount of pressure without cracking or breaking.

Common Types of Fasteners for Car Bumpers

When it comes to securing a car bumper, there are various bumper fastener types that mechanics and car enthusiasts use. Understanding the types of bumper clips and screws that suit your vehicle can ensure a more secure installation or repair.

Push Rivets

Push rivets are a common choice for attaching bumpers and other body panels. These fasteners feature a central pin that expands once pushed into the hole, securely holding the component in place. Push rivets are often used in bumper cover attachment and are known for their easy installation and removal.

• Advantages: Easy to install, requires no special tools, and can be reused in many cases.
• Uses: Ideal for quick, low-pressure installations like bumper trim repair or securing plastic fender clips.

Snap-In Retainers

Snap-in retainers are similar to push rivets but with a locking mechanism that snaps into place to secure the part. These retainers often provide a more secure fit, making them ideal for parts that need to withstand higher forces, such as bumper fastener rivets and certain car bumper components.

• Advantages: Stronger hold, less prone to loosening over time.
• Uses: Commonly found in plastic bumper filler or other car bumper repair applications.

Screw-In Fasteners

Screw-in fasteners feature threads that allow them to be tightened into place, providing a firm and reliable hold. These fasteners are typically used in areas where a more permanent attachment is needed, such as attaching the bumper trim or securing larger automotive screw types.

• Advantages: Provides a secure hold, especially in high-stress areas.
• Uses: Ideal for plastic screw anchors or thread cutting screws for permanent installations.

Bumper Fastener Rivets

Bumper fastener rivets are used specifically for securing bumper components where a tight, permanent attachment is needed. These rivets are often used in combination with other fasteners for extra security.

• Advantages: Secure hold, designed for heavy-duty applications.
• Uses: Bumper cover attachment, car wheel screws, and auto parts fasteners.

What Are Plastic Expansion Screws Used For?

Plastic expansion screws are used in applications where a fastener needs to expand to create a tighter fit within a hole. These screws are often used in DIY bumper fastener replacement when an exact fit is required.

• Advantages: Expand to fill larger gaps, offering a stronger hold.
• Uses: Common in bumper trim repair or attaching plastic car part screws to larger body panels.

Where Are Plastic Screws Used in Cars?

Plastic screws are used in various parts of a vehicle to secure bumpers, trim pieces, and interior panels. Some common areas where you’ll find car bumper screws include:

• Bumper Cover: Plastic bumper screw fasteners hold the outer bumper cover securely in place.
• Fender: Plastic fender clips attach the fender to the car body, preventing it from loosening.
• Car Body Panels: Used to hold panels securely in place while ensuring easy removal for repairs or upgrades.
• Interior Trim: Plastic car part screws are often used to attach dashboard panels, door moldings, and other interior features.

Installation and Removal of Plastic Screws

Knowing how to properly install and remove plastic screw fasteners is essential for anyone doing car bumper repair or other DIY car maintenance projects. Here’s a basic guide on installing and removing plastic screws:

Installation

1. Prepare the Fasteners: Make sure you have the right size and type of bumper fastener installation tools before starting.
2. Align the Components: Place the parts (bumper, fender, etc.) in the correct position on the car body.
3. Insert the Plastic Screw: Carefully insert the plastic screw into the hole, ensuring that it aligns properly.
4. Tighten the Screw: Use the appropriate tool (e.g., screwdriver, wrench) to tighten the screw, but don’t over-tighten, as this could damage the plastic.

Removal

1. Locate the Screw: Find the plastic screw that needs to be removed.
2. Loosen the Fastener: Use a screwdriver or the appropriate tool to loosen the screw.
3. Remove the Screw: Once loosened, remove the screw carefully to avoid damaging surrounding components.

Note: Always check for bumper clip damage signs before reusing plastic fasteners. If the screw or clip is cracked or worn out, replace it with a new one to ensure a secure fit.

When Should You Replace Plastic Fasteners?

Over time, plastic screws can wear out, especially in areas where the car is frequently exposed to the elements. Here are some signs it’s time for a bumper clip replacement or plastic screw installation:

• Cracking or Fraying: If the screw is visibly cracked, it’s no longer safe to use.
• Loose or Wobbly Bumper: If the bumper feels loose, it’s a sign that the fasteners have worn out.
• Bumper Rattle: A rattling bumper often indicates that one or more fasteners have failed.

Replacing Plastic Fasteners: A Simple Guide

Replacing plastic screws and fasteners is easy and requires just a few tools. Here’s how you can DIY bumper fastener replacement:

1. Gather Your Tools: You’ll need a screwdriver, pliers, and replacement fasteners.
2. Remove the Damaged Fastener: Loosen and remove the old, damaged fastener.
3. Install the New Fastener: Insert the new plastic screw fastener into the appropriate hole and tighten it securely.
4. Test the Fit: Ensure that the bumper or panel is tightly secured and free of movement.

Conclusion

Plastic screws are a vital component in securing your car’s bumper and other parts. Whether you’re performing a simple car bumper installation or repairing plastic bumpers, understanding the various types of automotive bumper fasteners can make your repair tasks easier and more efficient. From push rivets to screw-in fasteners, each type serves a specific purpose to ensure your car stays in top condition.

By following the guidelines for installation and bumper fastener removal, you can keep your vehicle looking great and ensure its safety and longevity. Always use corrosion-resistant fasteners and replace damaged bumper clips or screws promptly to avoid issues like bumper rattle fix and other common repair headaches.
